Struct StatePartitionKey 

pub struct StatePartitionKey {
    pub operator_id: String,
    pub partition_id: u32,
    pub subtask_index: u32,
}

Unique identifier for a state partition.

Fields

operator_id: String

partition_id: u32

subtask_index: u32

Implementations

impl StatePartitionKey

pub fn new( operator_id: impl Into<String>, partition_id: u32, subtask_index: u32, ) -> Self

Create a new partition key.

pub fn to_prefix(&self) -> Vec<u8>

Serialize partition key to a byte prefix for namespacing state keys.

Trait Implementations

impl Clone for StatePartitionKey

fn clone(&self) -> StatePartitionKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatePartitionKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for StatePartitionKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StatePartitionKey

fn eq(&self, other: &StatePartitionKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
